The study looked at how exposure to Mancozeb affects the behavior and blood of African catfish juveniles. They found that different concentrations of Mancozeb caused the fish to have trouble breathing and lose their balance. The safe levels of Mancozeb varied, with lower levels being safer. The blood of the fish showed changes in red blood cell count, hemoglobin levels, and white blood cell count, depending on the concentration and duration of exposure. Some types of white blood cells fluctuated, while others stayed the same.
